    • Compounds given in Table 2 are representative of an array prepared from substituted benzoic acids as shown in Scheme 2 of Ref. 3, using several amide coupling conditions. Compounds given in Table 3 were prepared as shown in Scheme 1 of Ref. 3, also using a number of different amide coupling conditions. For 22-24, cyclopropylmethyl-amine in step a was replaced with 3-aminobenzonitrile.

    • 1,3 X-ray diffraction data were collected from the crystal at 100 K (using an Oxford Cryostream) at Daresbury Laboratory SRS (station 9.6) using an ADSC Q4R CCD detector. The data were processed with the HKL package (Otwinowski, Z.; Minor, W. Methods Enzymol. 1997, 276:Macromol. Crystallogr. A, 307) and CCP4 program suite (Bailey, S. Acta Crystallogr., 1994, D50, 760). The structure was solved using the native p38 coordinates (PDB entry 1WFC) as the initial model in refinement by REFMAC (Murshudov, G.; Vagin, A.; Dodson, E. Acta Crystallogr. 1997, D53, 240). The final R-factor achieved for the complex was 17.5%. Coordinates have been deposited in the PDB as entry 3D83. Figures were produced using Pymol (DeLano, W. L. DeLano Scientific, Palo Alto, CA, USA. http://www.pymol.org).

    • Experiments were performed at 25 °C on a BIAcore S51 instrument. Human unphosphorylated p38α (as used in the crystallography) was immobilised using random amine coupling onto a CM5 chip in the presence of SB-203580 at pH 5.3 in 50 mM NaAc at normally 3-4kRU. Compounds were titrated over p38α in 50 mM Hepes pH 7.4, 150 mM NaCl, 1% DMSO, typically in doubling or tripling dilutions from 3.7 μM. BIAcore software and Grafit were used to extract on- and off-rates to ensure consistency and reproducibility.
